Surface and sample prepn. before color measurement is of extreme importance and has a quant, effect on the color measurement. Delta E (on-site color measurement) assocd. with dark time yellowing is reversible. With white vinyl siding, reexposing a dark time yellowed sample to sunlight for a short time period will bleach the sample to its natural weathered color. When properly formulated and processed, samples contg. various impact modifiers are identical in weathering, color development, and impact retention.

These measurements can usually provide more information for the same amt. of effort and material thanthe more classical methods. The importance of locating a ductile-brittle transition temp, is demonstrated, as its location can be effected by aging, compositional variables, and other external factors. In many cases, a relationship between impact strength and fundamental mol. motions may be of secondary importance in practical applications because of the great no. of externa! variables which influence the response of polymers under impulse loading. The geometry of thetesting app. may be useful in locating weak impact areas in fabricated articles without resorting to cutting and testing specimens at various angles relative to polymer flow. The strong influence of both thickness and temp, on the impact response of compression-molded I materials is demonstrated. Observations of force-time and energy-time traces coupled with observations made on failed specimens help in detg. whether failure is brittle or ductile.

During the impact test performed using a modified drop dart type app. (Dynatup 8100), the breaking force increased due in part to an increase in stiffness of the specimens and then decreased due to a substantial decrease in plastic flow with lowering of the temp. The max. breaking force of modified PVC specimens occurred at temps. 35-50F lower and was 10-15% higher than that of unmodified PVC. The notched Izod test was found useful, with some limitations, for measuring the crack-arresting ability of the PVC compns.

The method involves applying an alkali to the plastic before it is burned. Most efficient retention of thehalogen is achieved when the mole ratio of alkali to the halogen is from about 0.4:1 to 1:1. For max. halogen retention, dispersion of the alkali material is important and most readily accomplished by spraying a coned, aq. soln. of the alkali on the matter to be burned. The combination of the halogen-contg. plastic in the presence of an alkali results in the formation of the halide of the metal constituent of the alkali. The metal halide may readily be removed from the incinerator along with the ash. The alkali employed should be selected from those contg. alkali and alk. earth metals which form halides having b.ps. well above the burning temp, of the incinerator.
